Abstract: PURPOSE: To efficiently generate an optical frequency visible light laser beam having the frequency twice that of a fundamental light by forming an optical output part, which generates the fundamental light and an active nonlinear waveguide part which multiplies the frequency of the fundamental light monolithic alloy. CONSTITUTION: When a lasing active layer, contained in an active nonlinear waveguide part 103 absorbs a fundamental light transferred through the upper part surface of a multilayer optical output part 102, the fundamental light guided by this is reflected on a cleaved mirror. Then at the lasing active layer, waves of TE and TM types propagating in two mutually opposite directions are generated, and the waves advancing in mutually opposite directions eventually release frequency-doubled light propagating in the vertical direction (grow direction) to the surface of the waveguide.  With the thickness of each layer of active nonlinear waveguide part 103 being λ2 ω/2n (λ2 ω represents the wavelength of the frequency-doubled light, and n represents the index of refraction of each layer) for the fundamental light to be converted efficiently into frequency- doubled light, a semiconductor heterogeneous structure laser efficiently generates visible light of high frequency.
